of Frederick-,in theI county of, Frederick andj State of Maryland, haveinventedeertain new and useful: Improvements in Al V, [a I 1ufacturin gPaper Tubes, of which the following is a speciioationz-v i y The objectof my invention, mainly,4 is to :manufacture tubes from a strip orstrips ofpavper by one continuous connected operation 5 I and, further,to sever the tube into blanks of k lengths vsuitable ,for` boxes byautomatically-A -operating mechanism.A

' My invention .consists in ay novel organiza-` tion of mechanism, andin certain constructions .ofparts and 'combinations of devices, v whichwill hereinafter specifically be designated.

In the accompanying drawings I have shown all my improvements asembodied in the best Way now known to me. Obviously, however, some oftheparts may be used without the t others, and inmachinesjdiiferingsomewhat from the one .therein shown and herein described.

` The 'details of construction 'of portions of vthe mechanism forcarryingout my, invention may be varied inv some .respects` without de-lparting from the spirit of my vinvention,"which variation'swould bereadily suggested to skillful mechanics, or thoseskilled in the artto,which my invention pertains, simply by 11e-ending*this specificationand examining g vthe drawinin which- Figure 1 is a plan ervtop view withthe .camdrum in the position assumed just previousto n the time ofretractingthe mandrelfs'ectionrst withdrawn; Fig. 2, a side elevationwithythe cam-drum inthe same position.;l Fig 3, an elevation of thedelivery end of the machine,or

series oi' cams On the forward movement ofi fthe mandrel, aJpartialrotat'ion is imparted. to

it (all the sections caused to turn together reason of their abuttingedges) by means of la pin orroller-stud, rn, secured to the-end lofltheg I core Il., and vengaging with La spiral slot, n, ini

a liollowshaft or sleeve, N, rigidly connected with `or forming part loftheshaft l, before-mentioned. This tubular -shaftN is heldstationary ,1

during the advance lof the mandrel, and pref vented from rotating in theWrong direction,

Aby a ratchet-wheel, N, and pawl N?, piv-.

oted at nz-to the frame or base-plate in suitable manner. This pawl iskept in contact with the ratchet by its weight alone; but rai V-springmay be employed, if desired. To .pre-f;

vent accidental rotation of. the mandrel in;I

vthewrong direction, and guard against .its re- I volving on thebackward movement, a ratchetengaged by a broad-faced'pawl, O, which.admits ofthe reciprocation of the mandrel without clearing the wheelfrom the pawl,'fas well asallows the mandrel freely to be revolved inthe proper direction. The same pivot, n2. as that-by which the pawl Nzishinged to the frame serves also to fsupportvthis pawl 10'.'

It will be seen that on 'the advance of the mandrel thesleeve Nisheldfromrotating by its pawl, and thek mandrel forced to revolve,

while on the return stroke the Asleeve revolves, -and the mandrel is-kprevented from turning. By increasing or lessening the length of' theAslot nl, and giving a lon-ger or :shorter stroke 'to the mandrel, or bygivinga greater or lessij pitch to this slot, the :amount of turn-:given to the mandrel may be increased or diminished at will, as iswell understood. :The pivoted. iframes L Ll L2 -carry rollers p p1pyrespectively, which project into `the tracks or kgrooves I P P1 P2ofthe cam-drum .on the driving-shaft '0.' f

A corresponding portion,Q Q1 Q2., l.of each'-l groove is formed aliketo4operate on the roll- I ers of the respective liframes, toV advance theWhen thus Aad-v vanced, the straight parts R Rl R2Y of the grooves comein contact with the rollers simultaneously, and hold themandrelxstation#l ary in its advanced position for Aa `short while. Atthis moment a cutter severs from the tube that portion of its lengthprojecting beyond the mandrel, as will presently be explained. Next, theinclined portion S2 of the track P2 acts on the roller p, vibrates theframe L1 backward, and retraots the section h1,- next, the correspondingportion S1 of the track P1 comes in contact with the roller of the framelike portion, S, of the cam l? runs on the roller p, and moves'back thesection li, thus completing the. backward reei-procation of the man-Fdrel, vand' leaving vit ready to beV again Iadvan'oed,gas described, torepeatitsreciprocation.

Thesblanks .fare severed from the tube by a cutter, T, (shown asv'composed of a `circular saw or toothed disk,) which is thrown intoop-4'eration at the proper time-thatis, when the mandrel is advanced LsoasV to out closeito vits end, land prevent injuryto the tube. When thecut-away or recessed Apart u of a cam,.U,.on the `shaftfG ycomes incontact .with raroller, T, .on the saw-frame T2, .the weightk oftheframe causes -it` to :descend vand. bring the .saw to the tube advancedfrom the mandrel.. The. frame is held felevated while .the roller moves`in contact with they regulary lsurface of the cam.

-Thejcutter is rapidly rotated by a belt passing -around a pulley, V,onl the sawarborfand around `a corresponding pulley, V', on the shaftW,'on whichthe cutter-frame rocks. A pulley, W, on this shaft is driven bya k'belt 'passing from the driving-shaft, or driven in any Yothersuitable way. v

- The operation of my machine .will readily be seen .from the foregoingdescription, itbeing understood .that the main `shaft is revolved .bypower applied in` any -of the usual-Ways. As described, by myimprovements a tube is automatically formed and severed into lengthssuitable for box-blanks from two strips of paper passing tothe mandrelVat an .acute .angle therewith, and drawn forward (and woundv thereon insuch manner that the ledges of each .strip abut but do not overlap, thetop .strip being caused to `adhere throughout its entire -un der`surface to the inner stri-p,and thus form Y tubes of a `doublethickness of paper, with smooth, yclose joints. It is obvious, however,

that by changing the .location of the paperfcarrying, .frame relativelyto that. of the many'drel the strips might be caused to lap kat theiredges, and this lapbe increased .to `anydesiredl extent, simply byadjusting. the Jpaper-carrying-frame or roller to :a .positionfwhiohwill cause the -paper to be presentedto the man- -rdrel more nearly :atal right angle therewith. It is valso v.manifest thatra tube may be madeup fof-a single strip of paper by applying the paste .to-the under. sideof the overlapping frontedge of the strip. Obviously'the pastetrough maybe lessened in length to'so apply thepa'ste. y e l' l'alvhree lor even`more stripsmay be wound upon the mandrel together, `and. pastefapp'liedtothe. under .siu'face of all exceptl the yinner one, to make verystrong tubes; or `a seriesof strips, each pasted. upon itself at its overlap.vping edges, with or without uniting layers of paste between thedifferent tubes, may be made. f

The angle formed by the paper-carrying or roller frameand the mandrelmay readily be Vchanged by means of a slot and set-screw, as shown indotted lines in Fig. 1, the pin or .screw w (shown` inl full `lines in"is'aidfigure)v serving as `a center frame.
